About SeamGrid
A calm place for precise sewing plans.
SeamGrid is a Prospr Ventures project with browser-local sewing calculators and planning tools for people who work from measurements and want their data to stay on their own device.
What SeamGrid does
SeamGrid turns the finished dimensions you want into practical cut and planning guidance for projects such as boxy pouches, ruffles, and bias binding.
There are no accounts, no server-side uploads, and no payments. Inputs stay in the browser so planning stays quick and low-friction.
Made for clarity
Each published language has its own terminology, examples, and guidance so planning stays clear in the language you choose.
The focus is on calm, direct tools rather than accounts, uploads, or unnecessary steps.
Plan with care
Fabric, interfacing, zipper construction, and sewing technique can change finished dimensions. Use calculations as planning guidance, check your scale, and sew a test piece before cutting special fabric.
A calculator does not replace your own checks: compare measurements and seam allowances with your method and materials.
